STMicroelectronics STEVAL-MKI109V3 Evaluation Board

The STEVAL-MKI109V3 Professional MEMS Tool motherboard from STMicroelectronics is a complete, ready-to-use platform for evaluating ST MEMS sensors, acting as a bridge between MEMS adapter boards and a PC via USB to enable rapid testing of sensor behavior in realistic conditions. Built around a high-performance STM32F401VE 32-bit microcontroller, the board provides flexible power management with software-adjustable sensor supply voltages from 0 to 3.6 V, allowing you to replicate operating conditions from your intended application. MEMS adapter pins are exposed at connectors J1 and J3, so you can swap sensors on the professional MEMS tool without altering the motherboard, while Unico software support integrates configuration and measurement workflows for ST MEMS devices. For programming, you can reflash the board via ST-LINK through header J6 or connect over USB and use STM32CubeProgrammer in DFU mode, providing convenient firmware updates. The STEVAL-MKI109V3 is designed specifically to monitor the behavior of ST MEMS sensors and accelerate development by offering a dedicated, platform-wide environment for sensor evaluation and characterization.
